IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Iletiers Patent No. 39,052, dated June 30, 1863.

plied to use a certain new and useful Improvement in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and ex'- act description of my said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure 1 is a plan of said fastener, and Fig. 2 is a vertical section of the same.

Similar letters denote the same parts.

-The nature of my said invention consists in apcculiar construction of joint at the back e xd of the lever at the point of connection to the plate on the sash, whereby greater strength is obtained at this point than heretofore, at the same time that the parts are very easily and cheaply constructed, and I make use of a short helical spring around the fulcrum-pin of this lever to keep the parts in contact with suincient friction to prevent the parts becoming too loose.

In the drawings, a is a plate with a flange, b, in which is a circular recess at-Lta-lriug one side of the hub 2 ofthe lever 'oi 3 is a iiange around this hub 2, setting upon the top edge of this ange b, and d is a pin or screw passing through the lever c and plate a, and connecting the parts together. I prefer that said pin should be riveted up. The

hub 2 is hollow, and contains a helical spring, y

4, which, setting around the pin d and restir g at the lower end upon the plate a, produces a sufficient friction to hold the .lever c in any position in which it may be placed.

e is the plate ou the other part of the sashor casing to the plate a, and over which plate the said lever c is turned to secure the sa'shes'.y

The construction of this plate a, with the ange b and recess 1, strengthens said plate, and the hub 2 and iiange 3, Setting within the recess, with the latterabove` the edge of this ange,'make a very secure joint that is not I 2. The hollow hub 2 and spring 4, to retain l the lever c in position,jas specified.

In witness whereof I have hereunto set my signature this 6th day of- May, 1863.
